VIC EMANUAL 'JOSSENBERG-ER, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF T HIRTY-NINE PER CENT. TO EDWIN E. HAWLEY, F LOS ANGELES, CALI- i Fomvm.

vTo all whom t may concern Be tfknown that I, Vio EMANUAL Jos- SENBERGER, a citizen of the United States, (and a resident of Los Angeles. in the county fof Los Angeles and State 'of California, Yhave -invented certain new and useful Improvementsin Motor-Mountings for Aerial Vehicles, of which the following is a speciication.

Myr invention is an improvement in motor mountings for aerialvehicles, .and has for its object to provide in-vehicles of the character specified a mounting such 'that the axis of the propeller maybe shifted to shift the plane of the `propeller and the direction ofthe pull, to overcome emergencies o f every character, such as, for-instance, to

vin

"right the machine .fin nose dives, nose spins, tail spins, side slip ormaple leaf, and for permitting the machine to be exttrcated from airv pockets and to assist in rising and in landing.

g In the drawings:

Figure 1 is aside view of anaerial-vehicle providedwith the improved motor mounty mechanism;

" of the guides;-

,Fig. 5 is a partialperspective View of one Figs. 6 and 7 'are diagrammatic views showimg the manner of-operation of the device.

The present embodiment of the invention [is shown in connection with an aerial vehicle l of any usual or desired construc-v tion, the. said vehicle having the supporting planes 2, the vertical rudder 3 and the horizontal rudder 4, the said horizontal rudder vvbeing movable and having oppositely eX- tending arms 5, whose ends are connected lwith controlling .members 6 for swinging any usual or desired construction drives the propeller shaft to which is secured the propeller 9. y y

This motor'is supported by the base or bed shown injFig. 3.' The saidbed is asubstantially .rectangular'frama consisting -fof the journal pins.

- circle andbeing arranged with its rounded surface downward. Each of the said end members or segments carries a journal lpin 14.

The motor rests within the bed or frame, between the members 1-1, 12 and 13, and the member 13 has the lower section 15 of a bearing for the propeller shaft 8. The'journal pins 14 are journaled in bearings on the lframe of the vehicle, and detachable bearing sections are provided for engaging It `will be evident from the above lthat thel entire motor and its bed may swing on the journal pins to var'y the inclination of the axis of the propeller.

Each of the end members 11 of the bed has av ser-ies of gear teeth 18 concentric with the journal pin 16, and each series of teeth is engaged by the teeth of a rack bar 19.\ Theserack bars are mounted to slide in guiding shoes 2() shown more particularly in Fig. 19, each guiding shoe having overlying langes for engaging `rthe rack bar as shown in Fig. 2.

The lrack bars' are of inverted 'l`shape,

and the overlying iianges `of the shoes 20 engage over the extended edges of the rack bars.v Each rack bar is connected by a link 21 with a radial arm 22 on a controlling shaft 23 which is journaled in suitable supports in the frame, and a lever 24 is connected with the shaft for operating the shaft.

This lever is connected with the upper Fig. 4, the shaft 23 is square and engages 100 square openings in the radial arms 22. At its center it has a loopv 26 through which passes the lever 24, and the lever is pivoted to the loop'by a pivot pin 27.

The flexible members 6 are connectedto stirrups 28 pivoted to the lever, and the flexible members are connected with eyes "29 which are arranged at opposite'sides of the lever. It will be obvious that afl/separate control might be provided for the motoi` 2, if desired, to shift the same independently of theshifting of the ailerons and the horizontal rudder.

In ascending, the axis of the propeller will be inclined upwardly, until the desired height is reached, when it will be inclined toward the horizontal, attening out the flight of the vehicle. In nose spins or nose dives, the propeller axis may be shifted to positively and quickly shift the nose of the vehicle to prevent suchnose spin, and to'overcome lthe nose dive. It will be obvious that with the shifting axis or independent motor bed, a much more perfect control is permitted over the movements of the vehicle than in the usual case.

I claim:

In an aerial vehicle, the combination with the motor and the propeller shaft, of a bed on which the motor is mounted, saidv bed having oppositely extending alined journal pins whose axis is transverse to the axis of the motor shaft, said pins being journaled in fixed supports, the bed having depending toothed segments, and a rack bar for each segment, fixed guides for the rack bars, said bars meshing with the teeth of the segments, and means for simultaneously moving the bars, a shaft having cranks connected with the rack bars, a lever extending transversely of the shaft for oscillating` the same intermediate the ends thereof, flexible connections between the lever above and below the shaft and the control for the elevating planes.
